Self-strangulation by ligature is distinctly uncommon. It is distinct from self-suspension in cases of hanging, the latter being a far more common form of suicide. Self-strangulation must be separated from homicidal strangulation and from accidental sexual asphyxia. The ligature in suicidal strangulation may be knotted or tightened like a tourniquet. As the ligature is tightened the face and neck may become congested due to slow venous compression. Laryngeal fractures are rare and injuries are mild and often confined to the single ligature mark around the neck. The three cases discussed here were initially treated by the police as suspicious. Detailed examination of the scene and of the deceased person, along with investigation of the circumstances leading to the death, produced clear verdicts of suicide in all three cases.
通过绳索进行自我勒颈极为罕见。它与上吊自杀中的自我悬吊不同，后者是更为常见的自杀形式。自我勒颈必须与他杀勒颈以及意外性窒息相区分。自杀性勒颈时使用的绳索可能会打结或像止血带一样收紧。随着绳索收紧，由于静脉受压缓慢，面部和颈部可能会充血。喉部骨折罕见，损伤较轻，通常仅限于颈部的单一勒痕。这里讨论的三起案件最初被警方视为可疑案件。对现场和死者进行详细检查，以及对导致死亡的情况进行调查后，所有三起案件均得出了明确的自杀结论。
